Ok I bought an nv5600 and swapped into my 08 cummins. I done reading when I first installed it and seen 5 qts so I put 6qts through the top never checked it till the other day. And it was barely under the top bolt of pto cover. But I wanted to change the oil any ways so I ordered 8 qts of pens senchromesh so I wasn't shorted any oil. Pulled the drivers side cover off and drained it and and cleaned it all out good. I went ahead and filled through the top pto cover bolt. I wasn't able to get every bit of oil out of the qts. I ended up putting all 8 qts through the Top cover bolt. I drained what was left in the other qts into one. It's about a half a qt. so I put 7.5 qts through the top pto cover bolt. Also These are stock pto covers not coolers. Should I buy more oil fill it till it comes out. Then put one more through the top. I just don't understand how so much went in the top hole when everyone else reports so much less. Thanks guys

 

from what i know, it takes 6 qts

 

from what I have read its 5 qts stock by filling through the normal fill port. then 1or2 through the / top. I put 8in through the side. on level ground

 

as long as it dont build pressure a little over full wont hurt anything. what did you do with the g56 pot alum.

 

welded the bell up and installed one in my 12v. from what see 500- 600 hp is. to much for the g56. andthe otherg56 I weled it up and sitting in the shop floor. 2 in a year was to many for me. so I opted for other options this time.

 

i hear that
